The U.S. Treasury Department said it sets limits while allowing the nation’s intelligence agencies to access reports that banks file on suspicious or large money moves by customers, including information about Americans.

The Treasury, saying it was responding to a public records request, released the protocol at the end of last week, describing how it provides some information in bulk to the National Counterterrorism Center, the hub of the government’s anti-terrorism intelligence efforts. The document, partially redacted, also sets conditions for searching the database.
